Split a ","-joined string back to a vector (generic ggDNAvis helper)

Takes a string (character) produced by vector_to_string() and recreates the vector.

Note that if a vector of multiple strings is input (e.g. c("1,2,3", "9,8,7")) the output will be a single concatenated vector (e.g. c(1, 2, 3, 9, 8, 7)).

If the desired output is a list of vectors, try lapply() e.g. lapply(c("1,2,3", "9,8,7"), string_to_vector) returns list(c(1, 2, 3), c(9, 8, 7)).

Usage

string_to_vector(string, type = "numeric", sep = ",")

Arguments

string

character. A comma-separated string (e.g. "1,2,3") to convert back to a vector.

type

character. The type of the vector to be returned i.e. "numeric" (default), "character", or "logical".

sep

character. The character used to separate values in the string. Defaults to ",". Do not set to anything that might occur within one of the values.

Value

<type> vector. The resulting vector (e.g. c(1, 2, 3)).

Examples

## String to numeric vector (default)
string_to_vector("1,2,3,4")
#> [1] 1 2 3 4
string_to_vector("1,2,3,4", type = "numeric")
#> [1] 1 2 3 4
string_to_vector("1;2;3;4", sep = ";")
#> [1] 1 2 3 4

## String to character vector
string_to_vector("A,B,C,D", type = "character")
#> [1] "A" "B" "C" "D"

## String to logical vector
string_to_vector("TRUE FALSE TRUE", type = "logical", sep = " ")
#> [1]  TRUE FALSE  TRUE

## By default, vector inputs are concatenated
string_to_vector(c("1,2,3", "4,5,6"))
#> [1] 1 2 3 4 5 6

## To create a list of vector outputs, use lapply()
lapply(c("1,2,3", "4,5,6"), string_to_vector)
#> [[1]]
#> [1] 1 2 3
#> 
#> [[2]]
#> [1] 4 5 6
#>
